The full cost to own a home in Houston, TX runs well past principal and interest. On a $350,000 purchase with 5 percent down, the loan payment itself is roughly two thirds of the monthly total. Property taxes near 2.0 to 2.2 percent of value, homeowners insurance that prices high on the Gulf Coast, mortgage insurance, and in many suburbs a MUD assessment make up the rest. Budget for the whole number, not the loan payment, and figures shown are illustrative and subject to a full loan estimate.
The cost to own a home in Houston, TX is the number that surprises people, and it almost never surprises them in the direction they hoped. Texas collects no state income tax, and the trade-off shows up on your escrow statement every single month. I have spent more than twenty years writing loans across this metro, and the conversation I have most often is not about the interest rate. It is about the gap between the payment a buyer calculated on a mortgage calculator and the payment that actually shows up. This guide closes that gap with real Houston numbers. If you want the wider market picture first, start with my Houston home loans guide.
What Goes Into the Cost to Own a Home in Houston, TX?
Lenders talk about PITI, which stands for principal, interest, taxes, and insurance. That acronym is where most buyers stop, and in Houston it is only about four fifths of the story. Two local line items get left out often enough to derail a pre-approval: a municipal utility district assessment in master-planned communities, and flood insurance on a property inside a special flood hazard area.
Here is the complete list of what your monthly housing number is built from, in the order underwriting looks at it:
- Principal and interest, the loan payment itself
- Property taxes, collected monthly into escrow and paid to the county in January
- Homeowners insurance, also escrowed, and priced for wind, hail, and named storms
- Mortgage insurance, on conventional loans below 20 percent down, cancelable later
- Flood insurance, required by the lender inside an SFHA and worth carrying outside one
- MUD assessment, folded into your tax rate in many Houston-area suburbs
- HOA dues, not escrowed but counted in your debt-to-income ratio
Every one of those except HOA dues and maintenance flows through your escrow account, which is why your payment can change at renewal even on a fixed-rate loan. The rate is fixed. The escrow is not.
The Monthly Breakdown on a $350,000 Houston Home
The Houston metro median sale price has been sitting near $350,000, so that is the house we will model. Assume 5 percent down, a 30-year fixed loan, and an illustrative rate of 6.5 percent. Watch what share of the total the loan payment actually represents.
| Line item | Monthly | How it is calculated |
|---|---|---|
| Principal and interest | About $2,100 | $332,500 loan, 30-year fixed, illustrative 6.5% |
| Property taxes | About $610 | Roughly 2.1% of value, before homestead exemption |
| Homeowners insurance | About $325 | Near $3,900 a year, typical Houston range |
| Mortgage insurance | About $140 | Conventional at 95% loan to value, cancels with equity |
| Monthly total | About $3,175 | Before flood, MUD, HOA, or maintenance |
| Flood insurance, if in an SFHA | Add $80 to $150 | Varies by zone, elevation, and claim history |
| MUD, in many suburbs | Add $150 to $290 | Already inside the tax rate where it applies |
| Maintenance reserve | Set aside $290 to $580 | The common 1% to 2% of value per year rule |

Read the first row against the fifth. Principal and interest are roughly 66 percent of that monthly total, which means about a third of your payment has nothing to do with your interest rate. In a lower-tax, lower-insurance state that share would be closer to 80 percent. That single ratio is the whole reason a national mortgage calculator underestimates the cost to own a home in Houston, TX.
Property Taxes: The Largest Non-Loan Line Item
Combined tax rates across Harris County commonly land between 2.0 and 2.6 percent of appraised value once you stack the county, the school district, the city or ESD, the community college, and any utility district. On a $350,000 home, each tenth of a percent is about $29 a month, so the difference between two otherwise identical houses in different districts can be $150 a month or more.
Two protections matter, and both require you to file. The Texas homestead exemption removes a large slice of your home’s value from school district taxation on your primary residence, which is the single biggest reduction available to most owners. The homestead cap then limits how much your taxable value can rise year over year once the exemption is in place. Neither is automatic. You file with your appraisal district after closing, and I remind every client to do it in January. For how county lines change the math, see my Harris County home loans guide and the Fort Bend County guide.
One underwriting detail that catches new-construction buyers. If the seller was a builder and the land was taxed unimproved last year, the tax bill on record is far lower than what you will actually owe. A careful lender qualifies you on the fully assessed figure, not last year’s dirt taxes, which protects you from an escrow shortfall that shows up in year two.

Send me an address or even a neighborhood, and I will pull the actual tax rate, get an insurance estimate, check the flood zone, and build the full monthly payment before you write an offer.
Homeowners Insurance, Flood, and Wind
Texas homeowners premiums run well above the national average, and Houston sits at the expensive end of Texas because of hail, wind, and named-storm exposure. Planning near $3,500 to $4,500 a year on a mid-priced home is realistic, and older roofs, prior claims, and coastal proximity push it higher. Get a quote during your option period rather than a week before closing, because an unexpected premium changes your debt-to-income ratio at the worst possible moment.
Flood is a separate policy and a separate decision. Inside a special flood hazard area your lender will require it, and premiums swing widely with elevation, foundation type, and claim history. Outside an SFHA it is optional, and a meaningful share of Houston flood claims have come from properties that were never mapped into one. Preferred-risk policies outside the zone are usually modest, and I have never had a client regret carrying it.
MUD Districts and HOA Dues
A municipal utility district funds water, sewer, and drainage in areas built outside city service, which describes much of Katy, Cypress, Fulshear, Spring, and the north and west suburbs. The MUD rate is folded into your total tax rate, so it does not appear as a separate bill, but it can add half a percentage point or more of assessed value each year. That is real money: roughly $150 a month on a $350,000 home at 0.5 percent. My Houston MUD tax guide explains how to look yours up before you fall in love with a floor plan.
HOA dues behave differently. They are not escrowed, so they never appear on your mortgage statement, but underwriting counts them in your qualifying ratio anyway. Houston master-planned communities commonly run $500 to $1,500 a year, and some amenity-heavy neighborhoods run higher. A townhome association with exterior maintenance can be several hundred a month. Bring the dues figure to your pre-approval conversation so the number you shop with is the number that survives underwriting.
Cost to Own a Home in Houston, TX at Three Price Points
Same assumptions as before: 5 percent down, 30-year fixed, an illustrative 6.5 percent rate, a 2.1 percent tax rate, and typical insurance. No MUD, no flood, no HOA in these totals, so treat each as a floor rather than a ceiling.
| Purchase price | P and I | Taxes and insurance | Monthly total |
|---|---|---|---|
| $250,000 | About $1,500 | About $680 | About $2,280 |
| $350,000 | About $2,100 | About $935 | About $3,175 |
| $450,000 | About $2,700 | About $1,180 | About $4,060 |
Monthly totals include estimated mortgage insurance at 5 percent down and exclude MUD, flood, HOA, and maintenance. Illustrative only, subject to a full loan estimate.
Notice that taxes and insurance grow right alongside price, so stretching $100,000 higher on the purchase costs you roughly $600 a month rather than the $500 the loan payment alone suggests. If you are weighing how much cash to bring in against that monthly, my guide to how much down payment you really need in Houston runs the trade-off, and debt-to-income ratio in Houston shows how underwriting turns that monthly into a price ceiling.
The Costs That Never Reach Your Mortgage Statement
Your escrow account handles taxes and insurance. It does not handle the rest of homeownership, and this is where first-year budgets usually break.
- Maintenance: plan 1 to 2 percent of value per year, or $292 to $583 monthly on a $350,000 home
- Cooling: Houston summers push electric bills to a seasonal peak that renters in small apartments underestimate
- Roof and HVAC: hail is a routine event here, and a deductible on a wind and hail claim is often a percentage of the dwelling coverage, not a flat amount
- Foundation and drainage: Gulf Coast clay soil moves, and watering a slab is a real maintenance task
- Closing costs up front: covered in my Houston closing costs guide, separate from the down payment
There is a counterweight worth stating plainly. Houston’s price levels remain moderate relative to income compared with most large metros, and Texas collects no state income tax, so a household earning a professional salary keeps more of each paycheck to put toward that payment. The cost to own a home in Houston, TX is front-loaded into taxes and insurance rather than into purchase price. Whether that trade works for you is arithmetic, and I would rather you run it before you shop. My buying versus renting comparison works the same math from the other direction.
How to Plan for the Cost to Own a Home in Houston, TX
First, get a property-specific tax rate, not a metro average. Why it matters: two homes at the same price in different districts can differ by $150 a month, which is worth more to your budget than a quarter point of rate.
Next, get an insurance quote during the option period. Why it matters: roof age and claim history can move a premium by thousands a year, and the premium feeds your qualifying ratio.
Then, check the flood zone and the MUD before you write the offer. Why it matters: both are knowable in an afternoon and both change your monthly payment, so neither belongs in the surprise category.
Finally, file your homestead exemption after closing. Why it matters: it is the single largest reduction most owners can claim, it caps future increases, and nobody files it for you. When you are ready to run real numbers, you can begin your application online, or compare structures in my Houston conventional loan guide.
Get Your Real Cost to Own a Home in Houston, TX
I will build the full monthly picture on the specific house you are considering: actual district tax rate, an insurance quote, flood zone status, MUD if it applies, HOA dues, and mortgage insurance if you are under 20 percent down. You get one honest number instead of a calculator estimate. More than twenty years in Houston-area lending and 365-plus five-star reviews stand behind that process.
